7.4.4 Integrated Solenoid Trolling
The Values selected for Function Code L1 in Section Section 5.7.2.1.2: Troll Solenoid L1 Function, are
approximations for the various types of Gears. The actual amount of current required for satisfactory
troll operation may differ from the preset Values.
Table 7-2: Troll Valve Adjustments provides typical current requirements for some of the ZF Gears. As
stated previously, the actual current required to provide satisfactory operation may differ slightly from
those listed. Table 7-2: Troll Valve Adjustments also lists the typical pressure range in bars during troll
operation.
The approach taken for adjusting the Trolling Valve may be based purely on Shaft RPM, where the L1
preset is used and the Value is increased or decreased based on the Shaft RPM only.
The most effective approach is to use a combination of the L1 preset, Shaft RPM and the
measurement of the current flowing to the proportional solenoid or pressure applied to the clutch
plate.
Regardless of which approach is used, always adjust the L1 preset to the appropriate Value prior to
adjusting the Troll Minimum L2 and Troll Maximum L3 Function Codes.
NOTE: It is strongly recommended that the Field Service Test Unit (P/N 1400) is utilized when adjusting the
Proportional Solenoid.
